Sprint Electric offers a comprehensive range of digital drives for AC slip ring/wound rotor motors. With output power up to 975kW, the JL/X range of digital drives is suited to retrofit applications for gantry and tower cranes.

The Dunkermotoren ultra-compact BGA 22 Ironless brushless DC motor is now available with a suitable gearbox, encoder and controller. This BGA 22x22 dCore option benefits from the innovative ironless, BGA axial flow design and provides users with advantages such as zero-cogging torque, low vibration and very low audible noise.

Ensuring compatibility with Siemens controllers from the S7-200 up to the S7-1500, Dunkermotoren's rotary brushless DC motor range now includes the option of the BG 65 model being available with an integrated Profinet interface. Thanks to function blocks this motor option is simple to integrate into PLC controllers.

Reported to be ideal for controlling DC motors used in heavy industry applications such as metal working, steel mills, mining, or the cement, rubber and plastics industries, Sprint Electric has extended is range PLX of digital DC drives up to 2250 Amps.

Leading manufacturer of geared motors and electronic drives, NORD Drivesystems, has joined GATE (German Airport Technology & Equipment), the German umbrella association for quality suppliers to the airport industry.

Technical experts from Danfoss Drives will demonstrate how installation of the VLT series of drives can ensure optimum efficiency in system design, reportedly providing significant energy saving performance with immediate results.

The ability of DC drives to regenerate energy under braking without the need for complex intermediate storage or power bridges is just one of the benefits of DC technology, says Gary Keen, sales director at Sprint Electric

Two major industry events took place in November. Following hard on the heels of the Motor Drives Systems Conference (MDS) in Solihull was the SPS Drives exhibition in Nuremberg. Andy Pye visited both and reviews the trends and key developments

High-precision small drives for the aerospace industry.
The quality management system (QMS) of maxon motor received certification according to the EN 9100 quality standard on October 23, 2012. The provider of high-precision drives and systems up to 500 W is therefore now officially a “specialist for the aerospace industry”.
